2) Which diseases have scientists developed a metabolic calculator for?

a. Heart disease b. Diabetes c. Both of the aboved. Neither of the above

Explanation: Scientists have developed an internet crystal ball which is a metabolic calculator for predicting patient risk of developing diabetes and heart disease accurately, as against traditional methods.

The tool will prompt patients to make changes to their lifestyle and avoid these illnesses.

The more specific information you can give to individuals at risk, the more they will understand it and be motivated to make some changes.

Doctors usually predict risk for cardiovascular disease, type 2 diabetes and stroke by looking for five factors: obesity, high fasting triglycerides, high blood pressure, low HDL (good) cholesterol and high fasting blood sugar.

Those with abnormalities in three of these have been found to have metabolic syndrome and told there were at risk for future problems when it came to health.

The traditional approach also fails to consider variables such as race, ethnicity and gender.

On the other hand, the metabolic crystal ball, weighs the traditional risk factors and also takes into account race, gender and ethnicity to produce an easy-to-understand metabolic severity score.

The online calculator's predictions lined up well with actual cases of cardiovascular disease and diabetes, and the new study further bears that out.

The study looked, retroactively, at outcomes in more than 13,000 people and found that the tool was a better risk predictor than the individual risk factors alone.

3) Which company declared TCS as the US partner of the year in the commercial category?

Explanation: SpaceX successfully launched and then retrieved its first recycled rocket on March30, 2017, a historic feat and the biggest yet in its bid to drive down costs and speed up flights.

It was the first time SpaceX founder Elon Musk tried to fly a booster that soared before on an orbital mission. The Falcon 9 core landed on the bull's-eye of the ocean platform following liftoff with a broadcasting satellite.

The repeat flights for a booster and rocket turnarounds of as little as 24 hours, perhaps by next year will work wonders. Land, refuel and then back up again is the modus operandi of these flights.

SpaceX refurbished and tested the 15-foot booster, still sporting its nine original engines. It nailed another vertical landing at sea on March 30 once it was finished boosting the satellite for the SES company of Luxembourg.

Blue Origin, an aerospace company started by another tech billionaire, Jeff Bezos, already has reflown a rocket.

Nasa also has shared the quest for rocket reusability.

SpaceX - which aims to launch up to six reused boosters this year, two of them with the yet-to-fly, super-sized Falcon Heavy in late summer - is familiar with uncharted territory.

Besides becoming the first commercial cargo hauler to the International Space Station, SpaceX is building a capsule to launch Nasa astronauts as soon as next year.

It's also working to fly two paying customers to the moon next year, and is developing the Red Dragon, a robotic spacecraft intended to launch to Mars in 2020 and land.

Musk's ultimate goal is to establish a human settlement on Mars.

Explanation: To tackle the burden of cancer and other NCDs, the government has planned a series of measures including setting up 20 state cancer institutes, investing INR 3000 crores.

Government has also launched universal screening of diabetes, hypertension and cancer in 2100 districts of India.

Work on cancer institutes was under way and setting up of each AIIMS institute in every state would incur a cost of INR 150 crore.

The Centre supplements the efforts of the state governments for improving healthcare including prevention, diagnosis and treatment of cancer.

At present, the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) being implemented under National Health Mission (NHM).

This is for interventions up to the district level includes awareness generation for Cancer prevention, screening, early detection and referral to an appropriate level institution for treatment.

In February, the health ministry also rolled out a massive free door-to-door screening programme for the early detection of cancer, heart disorders and diabetes, which account for over 35% of all deaths in India.

The programme is among the preventive-care measures planned by the health ministry, and is targeted at people in the age group of 30-69 years, who constitute almost 37% of the total population.

This population is also highly vulnerable to noncommunicable diseases (NCDs) like cancer and diabetes that are responsible for 55% of the premature mortality in the same age group.

NCD: Know More

Estimates show the prevalence of non-communicable diseases is fast growing in India.

Diseases like cancer and heart disorders are also causing significant mortality, whereas diabetes is leading to a huge socio-economic burden.

While over 26% of all deaths in India are from heart diseases, 7% are from cancer. In 2015, over 690 lakh cases of diabetes were reported in India.

Explanation: President Pranab Mukherjee has appointed Sunaina Singh, currently head of the English and Foreign Languages University (EFLU) in Hyderabad, as the new vice chancellor of Nalanda University.

As per rules, the president has to choose the vice-chancellor from a group of at least three names forwarded by the university’s governing board.

As per sources, 135 names were screened, while six applicants were called for interviews.

Nalanda University is a flagship initiative formed under India’s Act East policy, which was first proposed at the East Asia Summit in 2007.

It was envisioned as a project to evoke India’s historical and cultural linkages with South East Asia and beyond.

Earlier on January 27, President Mukherjee appointed computer scientist and former IIT Delhi board chairman, Vijay Bhatkar – who is also the president of the RSS-affiliated Vijnana Bharati – as the university’s chancellor.

The EFLU unfurled the national flag on a 108-feet flagpole – touted as the “tallest flagpole among all central universities in the country”.

In February 2016, the Union Ministry of Human Resource Development had said universities should fly the flag prominently in order to ‘instil a sense of patriotism’ in students.

Singh has also served as the president of the Shastri Indo-Canadian Institute from 2009 to 2011. Before that she was the chairperson of Osmania University’s English department.

The term of the university’s first vice-chancellor, Gopa Sabharwal ended on November 24.

Sabharwal’s original term ended in November 2015, but she was given a one-year term extension.

President Mukherjee, acting on the Modi government’s advice, had reconstituted the governing board by dissolving the Amartya Sen-led Nalanda Mentors Group, which had been operating as the board.

Claiming that he had not been consulted before the president made his decision, George Yeo, former Singapore foreign minister and then university chancellor, also resigned.

11) Which country is set to prohibit mining for gold and other metals?

Explanation: Lawmakers in El Salvador voted overwhelmingly on 29th March 2017 to prohibit all mining for gold and other metals.

This makes the country the first in the world to impose a nationwide ban on metal mining, environmental activists said.

Declaring that El Salvador’s fragile environment could not sustain metal mining operations, legislators across the political spectrum approved the ban, which had broad support, particularly from the influential Roman Catholic Church.

Supporters said the law was needed to protect the country’s dwindling supply of clean water.

The vote in the Legislative Assembly turned a decade-old moratorium on mining into law, halting efforts by international companies to tap the gold belt running across the northern provinces of El Salvador.

The law does not apply to quarrying or the mining of coal, salt and other nonmetallic substances.
